Analysis of the 113 issues of the National Association of Secondary School Principals (NASSP) Bulletin published from January 1970 through May 1982 revealed that 23 percent of the over 2,000 articles printed dealt with development of the educational program, 10 percent dealt with student behavior and discipline, and 10 percent covered general issues of education and secondary education. The principalship accounted for 9 percent of the articles, while 7 percent discussed leadership and management, another 7 percent dealt with staff supervision and development, and 6 percent concerned evaluation of the educational program and student progress. None of the other 12 topic areas accounted for more than 5 percent of the articles. Of the 2,500 authors represented, 41 percent were affiliated with colleges and universities and only 24 percent were actually secondary school principals. Females constituted 14 percent of the authors. The researcher concludes that this analysis reveals a number of biases in the content and authorship of the NASSP Bulletin, and that several pertinent topic areas have been neglected. (PGD)
